In the past, I’ve never changed the name of my computer. It just has the default name like Paul’s MacBook. It seems my current one is Paul’s MacBook (4). Not sure how it got 4 at the end since I don’t think I ever had 3 previous computers.
Anyway, is it perfectly fine to simply go into System Preferences > Sharing and change the Computer Name to whatever I want? I assume I won’t run into issues changing the name but figured I would double check.
